Be it known that I, XAVIER Go`s`snL1N, a"

citizen of the French Republic,"and.a resident of Harp'enden, in Hertfordshire, Eng- '5 land, have invented certain new and useful This invention relates to improvements inl apparatusl for treating rubber compounds and` refers particularly to apparatus for treating powdered vulcanizedL substances or waste rubber compounds.

Apparatus according. to this invention ing heat and pressure tov the contents of a series of molds .andmea'ns' for moving'saidmolds so that they all pass through the same cycle of operationsand so that each element of the cycle maybe continually operative.

is so arranged that as each mold is moved its contents will be (a) introduced'into a mold and heated before or after introduction, (6)

. One method of carrying this invention. into effect will be. described with reference` to the accompanying drawing which represents ddiagrammatically the apparatus emo e p lolds A .A1 A? A3 A4 A5 are supported on a series of platforms B and are connected t0- gether by means o f the connectors A. A press C 1s adapted to'receive a mold A and to exert a pressure on the contents thereof at the same time maintaining it in a heated condition. The press D is adapted tomainhead track E1. ,I When the claw E is loweredcomprises in combination means for apply-` In a preferred construction the apparatus tain the pressure upon the contentsv of the mold but allows or causes the mold and its vfinit.

the Efjare'adapted-tol engage with two "conical holes.,l in the' sides ,of the cover A". sojfthatr'thje cover` maybe rotated about the suspension v.points `E1 .and E2 to facilitate cleaningl operations. 3A. second claw-like membe'nF F1is` operated -by means of the .hydraulic vpress F2.

Both the claw-like members are adapted to remove the covers of the molds as will be more particularly described hereinafter.

A winch G is connected to the mold A*t by .means of the chain, rope or other connec- At the end of theseries of platforms B are track railsH upon which runs a truck or the'likefI-I1 which is adapted to receive the llast moldY such as A5 and to convey it back ment which is` now about to be described, it

is removed to the truck H1 and conveyed to the position of the mold A. The mold is then discharged. and after the cover has beencleaned the latter is placed'in front of the '.mold as illustrated and denoted by' the reference letter A1. rlhe winch G is then operated conveniently by the crank handle G2 to draw the molds toward it 'so that the mold A, pushing its cover before it is moved to the position A1 where the material is supplied to it conveniently by hand and while remaining in this position the mold is resting on a platform B which is maintained in a heated condition, 'by aheating device B1. The next movement of the winch brings the mold to the position A2 wherel it is actedupon by the press C, .so that the contents of the mold are subjected to pressure while being maintained at a vulcanizing tempera' ture. Following the treatment in the.press C the mold is next moved to the press D where the' pressure is still maintained but the mold is allowed or caused to cool. Conveniently, with further movement of the winch G, the mold is moved into theposi tion A4 where the claw F F1 is operated by the hydraulic ram .F2 to engage with the cover of the mold and pull or tear it there'- from. Before replacing the cover on the mold, distance pieces are placed upon the molds so that the cover remains raised as illustrated at A". The connector G1 is then removed from the mold at Ali and connected to the mold A4 as illustrated. The mold Ai is now transferred to the truck H1L whence it is removed to the position A and the foregoing cycle of operations is recommenced. It is to be noticed thatk the period of rest in each position of the mold is the same. If necessary the heating period can be increased by the use of one or more supplementary heating platforms.

Obviously various modifications may be madein carrying the invention into effect. For example, in place of the employment of platforms, such as B, a form of guide trackrail could be employed and for heating the mold A1 it could be drawn through an openended oven or similar heating apparatus.

Other modifications may be made, provided always that the spirit of the invention is not departed from.

What I claim as my invention and desire to secure by Letters Patent is 1. Apparatus for treating powdered vulcanized substances comprising in combination a plurality of molds, connectors between each adjacent mold, an intermittently moving winch, a connector between said winch and the end mold of the series, platforms supporting the molds, a press maintained at a vulcanizing temperature, a cooling press, covers for each mold, adjustable jaws which grip the covers to remove or replace them, and a carriage on which the end mold of the series may be placed after completing the process.

2. Apparatus for treating powdered vulcanized substances' comprising in combination a plurality of molds, connectors between each adjacent mold, an intermittently moving winch, a connector between said winch and the end mold of the series, platforms supporting the molds, a press main-- tained at a vulcanizing temperature, a cooling press, covers for the molds, adjustable jaws which grip the covers to remove or replace them, a movable traveler supporting the jaws, and a carriage on which the end mold of the series may be placed after completing the process.

3. Apparatus for treating powdered vul? canized substances comprising in combinariage on which the end mold of the series may be placed after completing the process.

4. Apparatus for treating powdered vulcanized substances comprising in combination a plurality of molds, connectors between each adjacent mold, an intermittently moving winch, a connector between said winch and the end mold of the series, platforms supporting the molds, a press maintained at a vulcanizing temperature, a cool-i ing press, a cover for each mold, adjustable jaws being pointed at their gripping por, tions, the covers having cavities adapted to receive the points of the aws and a movable traveler supporting the jaws, and a carriage on which the end mold of the series may be placed after completing the process.

5. Apparatus for treating powdered vulcanized substances comprising in combination a plurality of molds, connectors between each adjacent mold, an intermittently moving winch, a connector between said winch and the end mold of the series, platforms supporting the molds, a press maintained at a vulcanizing temperature, a cooling press, a cover for each mold, adjustable jaws being pointed at their gripping portions, the covers having cavities adapted to receive the points of the jaws and a movable traveler supporting the jaws, other jaws for removing the mold covers after the contents have been compressed, and a carriage on which the end mold of the series may be placed after completing the process.

In testimony whe'reof I have signed my name to this specication in the presence of two subscribing witnesses.
